What two numbers multiply to 516 and add up to -260?

Here we answer the question: "What two numbers multiply to 516 and add up to -260?"

The answer to your question is:

-258 and -2

Below we illustrate and prove that -258 and -2 multiply to 516 and add up to -260:

-258 × -2 = 516
-258 + -2 = -260

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² - 260x + 516 = 0

If so, the solution to factor the quadratic equation above is:

(x - 258 ) (x - 2)

To summarize, since -258 and -2 multiply to 516 and add up -260, you know that the following is true:

x² - 260x + 516 = (x - 258 ) (x - 2)
